The Allen Bradley part number 20BD248A3QNNANC0 is a specialized adjustable frequency AC drive designed for efficient motor management in demanding environments. It operates on a three-phase power supply at a voltage of 480 volts AC and handles a significant output current of up to 248 amps. This unit is rated to deliver an impressive 200 horsepower, making it suitable for heavy-duty applications.
With a standard input frequency of 60 Hz, the drive supports a maximum output frequency of 400 Hz, with the capability to extend to 420 Hz as an optional feature. The IP20 enclosure complies with NEMA/UL Type 1 standards, ensuring protection against dust and contact in controlled settings. Additionally, a conformal coating is applied to enhance durability by shielding the internal parts from moisture and contaminants.
The operational interface includes an LCD display and a full numeric keypad, allowing for intuitive monitoring and adjustments. Connectivity is facilitated through 6 digital inputs, 3 digital outputs, 2 analog inputs, and 2 analog outputs for flexible integration into existing systems. The drive also features encoder input capability powered at 12 V DC, dual-channel, with a maximum current of 250 mA, enhancing feedback for precise control. Note that this model does not incorporate an internal brake resistor or a brake IGBT, indicative of its design for applications that do not require these components.
